Lithops, also referred to as living stones, are succulents. This means they can store water and can survive with little moisture. They come from the large, southern African family called the Mesembryanthemaceae. Lithops may even produce daisy-like flowers in the fall, which can be yellow, orange or white. These flowers last for about two weeks. Growing lithops from seed is a simple project. There are 37 species of lithops to choose from and another 53 subspecies and varieties.
Fill a small 2 x 2-inch ceramic pot with cactus mix potting soil. Leave the soil 1/2-inch below the rim of the pot.
Water the soil until it is thoroughly saturated.
Place one seed per pot.
Cover the seeds with a layer of fine-grained sand, or using a tea strainer, sift some very fine potting soil over the seed to just barely cover them.
Mist the sand covering the seeds with water to moisten.
Place the ceramic pots into a container with a snap on lid.
Position the pots in a bright location, but not in direct sunlight.
Keep the soil moist by misting daily.
Uncover the lithops partially after two to three weeks. Leave the lid partially over the container for four weeks.
Reduce watering when the lithops reach a height of 2 inches. Water when the top 1/4 inch of soil is dry.
Transplant the lithops after one year.
Make sure the ceramic pot you choose has drainage holes at the bottom. You may wish to use tweezers to place the seeds onto the soil because of their small size. Choose a container with a clear lid so light can penetrate through and help retain humidity. When the lithops have been growing for 2.5 months, allow the soil to completely dry out before you water. Gradually increase the days between watering until you are watering them every two weeks. It can take the lithops seeds anywhere from three weeks to a year before they germinate. You can then transplant several lithops into a large pan. Fill in the spaces between the plants with matching grit and pebbles. Repot the lithops every two years.
Do not cover the seeds more than 1/4 inch deep.
